problem and license

[Aaronli888888]

There is a problem with multi-scale, and when will the MIT license be granted？

@WongKinYiu did you decide under which license you want to publish that project? I'm sure more people would adopt this awesome project when they have a license that clarifies allowed usage.

@WongKinYiu could you add a license?

@WongKinYiu I would also like a clarification on licensing for the repo

See #2 - the master branch follows the license of https://github.com/ultralytics/yolov3 which is GPL-3.
